This is part of the reason you're having trouble with the responses; it'd be hard to count the number of guys who post this type of response to questions about a crashed model wherein the radio system is blamed only to find out later, there is a power system problem not faulty radio gear.
Faulty radio gear is RARELY the case and if you tried browsing around or using the search engine here you'd know that rather than ASSuming you're the only one who's ever had this kind of issue and your attitude is not encouraging thoughtful responses.
